Answer:

Step-by-step explanation:

2 (4 - 3x) + (5x-2) can be solved in several basic steps. First, distribute multiplication in 2(4 - 3x), obtaining 8 - 6x and (overall) 8 - 6x + 5x - 2.

Combine like terms: -x = -10, or x = 10

The area of the region in the first quadrant between the graph of y = k*sin(x) and x-axis (where k > 0 ) on the closed interv

astraxan [27]

Note that $0\le k\sin x\le k$ in the given closed interval, so the area is exactly given by the definite integral

$\displaystyle\int_0^\pi k\sin x\,\mathrm dx$

(no absolute values needed!)

Integrating gives

$-k\cos x\bigg|_{x=0}^{x=\pi}=-k(\cos\pi-\cos0)=-k(-1-1)=2k$

Explain: What is the solution to this system of equations? 2x+y=20 6x-5y=12

bazaltina [42]

Answer:

solution set is (x,y) = (7,6)

Step-by-step explanation:

solving by substitution method

2x +y=20--------------1

6x-5y=12---------------2

from equation 1, solve for y

2x+y=20

y= 20-2x------equation 3

adding value of y in equation 2

6x-5y=12

6x-5(20-2x)=12

6x-100+10x=12

16x= 12+100

16x= 112

x= 112/16

x=7

adding value of x in equation 3

y= 20-2x

y= 20- 2(7)

y=20-14

y=6

so solution set (x,y) = (7,6)

Find the mean of the number set. 93, 81, 94, 78, 89, 92, 94, 99 Your answer divided by 7

dimaraw [331]

Answer:

mean= 90

Step-by-step explanation:

The mean is the terms added together, then divided by the number of terms (in this case, 8):

$93+81+94+78+89+92+94+99=720\\\\\frac{720}{8} =90$

Done.
